Answer:

(b-1)²-9​

= 4[(b - 1)(b - 1)] - 9

= 4[b² - b - b + 1] - 9

= 4(b² - 2b + 1) - 9

= 4b² - 8b + 4 - 9

= 4b² - 8b - 5

Hope this helps!

Suppose that Mr. Warren Buffet and Mr. Zhao Danyang agree to meet at a specified place between 12 pm and 1 pm. Suppose each pers
Natali [406]

Answer:  f(x)=1\ \text{where}\ 12\leq x\leq 13

Step-by-step explanation:

The probability distribution function for uniform distribution in interval [a,b] is given by :_

f(x)=\dfrac{1}{b-a}\ \text{where}\ a\leq x\leq b

Given : Mr. Warren Buffet and Mr. Zhao Danyang agree to meet at a specified place between 12 pm and 1 pm.

Since 1 pm comes after 12 pm, and in 24 hours system we call it as 13 pm.

If each person arrives between 12 pm and 1 pm at random with uniform probability, then the uniform distribution function for this will be :_

f(x)=\dfrac{1}{13-12}=1\ \text{where}\ 1\leq x\leq 12

Hence. the distribution function for the length of the time that the first to arrive has to wait for the other will be :-

f(x)=1\ \text{where}\ 12\leq x\leq 13

Find the value of each variable ​
aalyn [17]

Answer:

x = 12\sqrt{2}

y = 12

z = 12\sqrt{3}

Step-by-step explanation:

The triangle with z as one of it's sides is a 30, 60, 90 triangle where the longest side of the triangle is 2x, the shortest side as x, and the middle side as x*sqrt of 3.

The shared line between the two triangle is 12 and z is 12*sqrt of 3

The left triangle is a 45, 45, 90 triangle where the 2 sides that look the same are the same and the hypotenuse is x sqrt of 2 so y is 12 and x is 12 sqrt of 2
